Paul, who suffered the injury late in the Rockets‘ Game 5 victory on Thursday and missed Game 6, received treatment to attempt a return but a comeback was extremely unlikely. Paul is believed to have an elevated-grade hamstring strain, league sources said, making a recovery difficult within days of the injury.

Behind Paul’s spectacular Game 5 performance, the Rockets took a 3-2 series lead over the defending champion Warriors. Paul had 20 points, seven rebounds, six assists and four 3-pointers in Game 5, hitting several clutch shots, shimmying on Stephen Curry after a deep 3-pointer and supplying the Rockets with leadership and energy.

In Paul’s absence, the Rockets will continue to start Eric Gordon and extend the roles of Gerald Green and Luc Mbah a Moute.

Paul, a nine-time All-Star, joined the Rockets last summer and has teamed with All-Star and MVP favorite James Harden to lead Houston to the brink of the NBA Finals.
